What to check before ordering

Verify that your device supports the microSDXC form factor and the UHS-I bus. Confirm the host can take advantage of the U3, V30 and A2 speed classes for sustained write performance. The card operates between 2.7 V and 3.6 V and is rated for 10,000 mating cycles.

Questions about this item

Does the 256GB microSDXC T7 card come with an adapter or do I need to buy one separately?

The card is supplied as the microSDXC unit only; a full-size SD adapter is not included and must be purchased separately if your device requires it.

Should I choose this 256GB U3 V30 A2 model or a lower-capacity version for 4K video on my drone?

The 256GB capacity with U3 and V30 ratings guarantees sustained 30MB/s write speeds needed for 4K recording, while the A2 rating also speeds up app loading on drones and action cameras.

Will I actually see the 170MB/s read speed when the card is in my laptop's built-in slot?

The 170MB/s figure is the maximum sequential read speed over the UHS-I interface; real-world throughput depends on your laptop's card reader capabilities and file sizes.
